The Design Of A Virtual Oscillograph Based On Sound Card

Modern science and technology development changes with each new day, computer especially so. Powerful computer processing capacity has made it an excellent tool and its application has become increasingly widespread. While traditional equipment has got rapid development, the instrument accuracy is more and more high, the function is more and more strong, and the performance is more and more good, but the traditional instrument basically has not gotten rid of exclusive use and manual-operated pattern. The traditional table instrument is a closed structure defined by the factory. It has the fixed input/output interfaces and the instrument operation panels. Each kind of instrument only can carry out some specific survey functions, and provided to the user by the definite way. Our table instrument such as high-grade digital oscilloscope mainly relied on import. On the one hand these instruments processing technic is complex, manufacturer's level is high, and the production breakthrough has the difficulty. On the other hand, the user...
